Loki + Grafana: A Lightweight and Cost-Effective Logging Solution for the Cloud

We’re wrapping up our series on centralized logging with a modern and innovative solution: Loki together with Grafana. Developed by Grafana Labs, this stack reimagines how logging works — making it simple, efficient, and especially appealing for those already using Prometheus.
